| error | Longint | Error result

### Do not use this command in QPix v3 or later

This command is preserved in QPix v3 for backward compatibility reasons. The graphics importer quality has no meaning in QPix v3 and later.

Returns the current value of the drawing quality property of a graphics importer instance.

The graphics importer instance is specified by importerRef. If importerRef does not refer to an existing graphics importer instance, the qpx_paramErr error code is returned.

Drawing quality is returned as a value in drawingQuality in the range of 0..1024. Some graphics importers ignore this value to improve performance.

QPix defines the following drawing quality constants:

qpx_MinQuality | 0 | Minimal quality
qpx_LowQuality | 256 | Low quality
qpx_NormalQuality | 512 | Normal quality
qpx_HighQuality | 768 | High quality
qpx_MaxQuality | 1023 | Maximum quality
qpx_LosslessQuality | 1024 | Lossless quality

Example

``Get quality` `` `C_LONGINT($error)` `` `C_LONGINT(gQPixImporter;$quality)` `` `$error:=QPx_GetImporterQuality (gQPixImporter;$quality)` `` `If ($error#qpx_noErr)` ``Handle the error` `End if`
